Maniac Mansion: Ed's hamster and the electrical cattle prod

[BoyWonda]

Hey all

I remember there was a cutscene in Maniac Mansion in which Dr.Fred would request Ed's hamster as well as an electrical cattle prod. Nowadays when I play the game I don't get this cutscene anymore but I'd like to see it again;

Do you remember when it occurs? And if you need to perform certain actions to see it? (or if performing certain actions prevents you from seeing it??)
